Synchronous Generator Clause Samples
A Synchronous Generator clause defines the requirements and specifications for equipment that generates electricity in sync with the grid frequency. This clause typically outlines technical standards, performance criteria, and compliance obligations for the installation, operation, and maintenance of synchronous generators, such as those used in power plants or industrial facilities. By clearly setting these expectations, the clause ensures reliable integration of the generator into the electrical system and helps prevent operational issues related to frequency or phase mismatches.
Synchronous Generator. The generator is a synchronous type, air-cooled, three phase machine, brushless and weather protected. It is built to NEMA II specifications and rated at kW, 0.85 PF, 13.8 kV and 60 Hz. It is cooled by a once-through air-cooling system with an inlet filter. The generator and the two turbines are directly coupled.
Synchronous Generator. The generators shall provide their nominal power output within the range of 5% of their nominal voltage, at any operating point within a range of power factor of 0.9 lagging to 0.95 leading. The Seller shall provide information on the output capability of the generators at other power factors outside of this range. The electric generator associated with the turbine shall be of proven design with large number of units in operation connected to a 60 hertz grid experiencing high reliability record and comply with the ANSI/IEEE standards and their capacities shall match or exceed the nominal output of the corresponding turbine throughout the whole range of operating power factors and voltages specified below, over the full range of ambient temperatures specified. The insulation of the generator stator and field windings shall be non-hygroscopic, Class F type, complying with ANSI/IEEE standards, but having a rated load operating temperature not exceeding that of Class B under any operating condition within the specified output. The global vacuum pressure impregnation process shall not be utilized for the insulation system. Coils shall be of the B stage type or VPI type individually cured before insertion into the generator. The generator shall be hydrogen cooled or totally enclosed water-to-air cooled (TEWAC). The generator shall be provided with enclosure suitable for indoor or outdoor operation depending on the arrangement selected. . The cooling system shall be rated such that load reduction of the turbine generator is not required even under extreme ambient temperature conditions. The quality of the generators and accessories shall be in accordance with International Standardization Organization (ISO)-9001, EN 29001 or BS 5750 Part 1 and [other equivalent international quality standards].
Synchronous Generator. The mathematical model of the synchronous generator can be described with a vector diagram as show in Figure 24. Where;
